Simple Molecular Substance

Question 1

What are simple molecules substances

Answer 1

A few atoms joined together by covalent bonds

Question 2

Examples of simple molecular substances

Answer 2

Hydrogen as they just have one electron meaning they only need one to complete their first shell

Oxygen because they only need two electrons to complete their outer shell

Question 3

Properties of simple molecular substances

Answer 3

• Very strong covalent bonds but the forces of attraction between these bonds are weak
• to melt o’boyle a simple molecule compound you need to break the intermolecular bonds and not the convenient bond
• low boiling and melting points
• the bigger of the molecules are the stronger the intermolecular forces so the more energy needed to break them and the higher the melting and boiling point is
• can’t conduct electricity as there are no charged particles free to move around
